Before you switch from DSLR to mirrorless, know how they compare

Compare 7 key areas of DSLRs versus DMIL cameras

With the new Nikon Z series full-frame, digital mirrorless interchangeable lens cameras (DMIL) and Canon's new full-frame EOS R DMIL camera, Sony now has significant prosumer DMIL competition. Now that these manufacturers are fighting it out for supremacy in the quality DMIL market, I think we can expect that improvements in DMIL feature sets and image quality will accelerate significantly in upcoming years.

Major improvements are needed for electronic viewfinders, autofocus on fast-moving targets, battery life and low-light image quality, especially for future pro-level DMIL cameras.

If you're considering a move from DSLR to DMIL cameras, here are seven key areas you need to consider before making the change.

Nikon XQD based cameras have a future

Of the world's major Digital Single Lens Reflex (DSLR) and Mirrorless interchangeable lens camera (MILC) manufacturers, only Nikon DSLRs have utilized XQD memory cards to store images and videos. Some Sony video cameras also use XQD cards.

XQD cards were manufactured by Lexar and Sony, until June, 2017, when Lexar announced that they were discontinuing their retail memory card business, including XQD memory cards. Since then, only Sony has been manufacturing XQD cards.

The XQD card was created for high-definition camcorders and high resolution digital cameras, as it offered considerably better performance than Compact Flash memory cards, even CFast cards.

While Nikon bet on XQD cards, their competitors bet on CFast memory cards. Today it's clear that Nikon won their bet. Frankly, based on the different cards' specifications, I don't understand how CFast supporters thought they'd win their bet.

Identifying your travel photos when you return home - Part II

As discussed in Part I of this Photo Identification series, one of the most classic problems of the vacation photographer is identifying one's photographs after returning home. Often when you look at your photos weeks after making them, it can be difficult to remember where you took them, and what each image's subject is.

The low-tech identification methods discussed in Part I, such as written journals, marking maps with photo locations, and using identifier photographs work, but many photographers consider them too tedious and time consuming. There are some hi-tech identification methods which are automatic or close to it, but I caution anyone who thinks they are foolproof, to think again.

Each of these hi-tech methods involve GPS (global-positioning system) technology. GPS devices typically identify their position by longitude, latitude, altitude and compass heading, plus date and time.

Today, some digital cameras have built-in GPS units, some cameras are GPS ready, and other cameras can have GPS information added to their photos' exif data, but don't have the capability to embed the information directly themselves. It must be added later, via a computer.
